Preparation, pharmacokinetics and anti-obesity effects on dogs of nuciferine liposomes.

Background: Nuciferine (NUC), a natural compound extracted from lotus leaves, has been proven to have anti-obesity effects. However, the development and application of NUC as an anti-obesity drug in dogs are hindered due to its poor water solubility and low bioavailability.

Objective: To promote the development of NUC-related products for anti-obesity in dogs, this study prepared NUC into a liposome formulation and evaluated its characteristics, pharmacokinetics in dogs, and anti-obesity effects on high-fat diet dogs.
